REvoLvING FLUID-PRESSURE Moron.

' Be it known that I, HANS PAsCoLINI, a citizen of the United States, and a resident of Chicago, Cook County, Illinois, haveinvented av certain newfand useful Improve-V ment inRevolving Fluid-Pressure Motors, of which the following is a speciication. 'This invention relates to rotary or. revolving engines orlmotors'in 4which there arecyl-` Inders having pistons therein, and in which.

the cylinders rotate or revolve about an axis,

the pistons being connected to a stationary4 crank wherebyin/eifect vthe pistonsn reciprocate in the cylinders, but only relatively, inasmuch as practically' the entire engine Vor motor revolves about the'said axis and the' pistons in effect move back and-forth in-the cylinders because said crank is eccentrically located and is some distance fromsaid axis, and in reality the' cylinders move toward and away from said crank as'they revolve." a' f `Generally stated, they object of the inven' tion is to provide an improved constructionand arrangement whereby said pistons are double-acting, so to speak, fluid pressure being admitted at opposite sides ofeachpiston, whereby each piston is alwaysexerting pressure onV said stationary crank .to cause therotation or revolving motion of the en-l gine or motor; i' Y Y It is also an object to provide an improved construction or varrangei'ne'nt whereby the Y engine or motor is reversible at will.'V

section on Figure isr a detail view of the interior portion of the mechanism shown in Figure l7, showing the omitted parts in dotted lines. j As thus illustrated, the invention com? prises a plurality of cylinders 1 arranged as shownand preferably cast integrallywith each otherV and secured at their outer ends' tothe annular member2 which forms the rim of the wheel of which said cylinders are the-spokes, which has the spokes 3 `in addition, thus forming a body which is free to* rotate :onthe'bearing 4 carriedby thesta4 tionary crankshaft 5, thelatter being soli'd-y ly mounted in the bearings 6, in the'maniier shown. A-pulley wheel Y can be secured to one side of thef'wheel 'like' rotary body thus provided. `Pisto'ns' are providedf'in' said cylinders, having pistonv heads 9, togetherk with crossheads 10 which slidefin the guides 11 to prevent lateralthrust'on said piston crosshe'ad l0, whereby fluid`pressure exertedv onthe pistons inthe cylinders Vwill serve to rrods. 'Crank 12' of saidstationary'crank shaft is connected by ya pitman 13 with each rotate the wheellike body formed bythev cylinders and'sp'okes previously mentioned; For this purpose each cylinder is provided with ports I14 and 15 for admitting and ex-f-y 'Y Vhaustingy the fluid pressu`re, such as steamv or, 485 j compressed air, to and from the cylinders" to'exertthelnecessaryV pressure on the pistons thereinf' Passages '16 Va' n jl 17 connect` Y* the ports 14 `and 15 respectively 'withgthegi' valve mechanism at the center ofthe engine,

the luidpr'e'ssure beingl admitted tosaid'f mechanism through the pipe"l8,'eandt1jen j T admittedltosaid cylinders 'to'operate' the pistons therein. exhausted from the cylinders -through said passages'V to saidv valve ,Inecha-n'i'sm andv is allowed-"to escape :from ,the latterfthrough the? pipe 19, whereby'pressure -is firstl'ad- The, fluid pressure is then mitte'd'to yo 'ne side of each piston .and thenV the' other side thereof. lIn* this way, Vas

previously stated, the engine isfdouble act@` e. ing/so to speak,Y inasmuch as'thevfluid pressure .causesfeach piston -to first 'exerta'push f and athen aV pull onthensptationary c rank shaft. In other words, poweris developed` byQpea'ch stroke of each piston, regardless of` .4

whetherv the piston is moving toward-the inner end of the cylinder or toward the I outer vend thereof. Forthis purpose said valve `mechanism comprises .the cylindricalA portion 2O of .thev stationary''crankshaft.Y Y A` collar V21 is'stationary on. said portionk 20y said cylinder, adapted to reciprocate relatively therein, a stationary crank eccentric to said axis, means to connect the piston to said crank, and valve mechanism controlled bythe revolving motion of the cylinder to admit and exhaust fluid pressure to and from said cylinder at opposite sides of said piston, whereby said piston alternately exerts a push and then a pull on said crank to revolve the cylinder, said valve mechanism comprising a stationary cylindrical member upon which the engine rotates, With grooves in said member, collars on said member, With opposite openings in each collar, and passages to connect the cylinder change the speed and also to reverse the p engine.

5. A structure as specified 1n claim 3, said Vvalve mechanism having a singlehandle by which said mechanism is adjustable about :2.

the axis ofthe engine to control the speed thereofand to reverseV the direction of rotation.
